Uprating chaining fails

[MaxGhenis]

For example, we uprate the California dependent exemption by the California CPI:

And we uprate the California CPI by the IRS CPI (as it's only available through 2023):

https://github.com/PolicyEngine/policyengine-us/blob/master/policyengine_us/parameters/gov/states/ca/cpi.yaml

But the dependent exemption isn't uprated beyond 2023:
